Abstract

In early 2020, a new deadly virus was discovered that can spread quickly, called SARS-CoV-2 or Coronavirus Disease 2019 (COVID-19). Indonesia is a country with a relatively high number of survivors of COVID-19. The success of the Indonesian government in providing massive COVID-19 vaccinations can minimize the risk of death. The World Health Organization (WHO) stated it would revoke the Public Health Emergency of International Concern (PHEIC) status for COVID-19 in May 2023. However, many positive cases of Covid-19 were still found in Indonesia. Most of them are survivors who have not carried out complete vaccinations until they get a booster vaccine. This study analyzes public sentiment about booster vaccines in Indonesia using the Naïve Bayes classification algorithm. The results showed that the classification modeling accuracy had an excellent value of 97.51%. In contrast, based on the analysis results, the number of words that frequently appeared in the twelve highest word cloud visualization results found tokens that had positive sentiment values.

Abstract

Ducted propeller is a method on the propeller modification which added duct/nozzle on the propeller. Ducted propeller application is aimed to increase propeller thrust, increase propeller efficiency, and decrease propeller noise and vibration. In this research, a numerical simulation was conducted using ANSYS Fluent 2020 R2 with k-epsilon solver model. The aim of this research is to analyze the effect of the duct geometry using Ld/D (duct length/duct diameter) ratio. The simulation was done on two Ld/D variations at three different propeller angular velocity (1.000, 3.000, 5.000 rpm). The result of this research shows that duct with 0,6 Ld/D ratio has higher thrust force than duct with 0,5 Ld/D ratio. Meanwhile, the increase of propeller angular velocity increase propeller thrust force and fluid velocity.

Abstract

The utilization of coal as an energy source is still the main choice of the textile industry in Indonesia. The process of this utilization left 20% of FABA (fly ash-bottom ash) where 80% of them were bottom ashes which are considered hazardous and toxic waste. This study aims to obtain the technology and production process for treating bottom ash and biomass from urban waste as an alternative energy source and reducing environmental problems (zero waste: waste to energy and waste to material). Biomass Coal Fuel-Sludge (BCFS) Briquettes as a product derived from bottom ash, biomass, and biosludge had a composition of 50%: 30%: 20%. The briquettes utilization can reduce coal use by 16% and increase boiler temperature to 35°C - 75°C. The emission in the trial burning test which were the particulates, sulfur dioxide, and nitrogen dioxide met the quality standards required in the Technical Approval in the Sector of Hazardous Waste Management from the Ministry of Environment and Forestry. With this research, the BCFS briquette products can be a solution to the utilization of B3 waste and waste problems.

Abstract

The concentration of PM2.5 in ambient air is one of the indicators of air quality that affects public health. This pollutant is considered hazardous due to its small size, which allows it to enter the lungs and remain suspended in the air for a considerable amount of time. Identifying the patterns of PM2.5 concentration distribution is important to recognize the influential factors in increasing PM2.5 concentrations, thus enabling better formulation of solutions. This study analyzed the patterns of PM2.5 concentrations in three ASEAN countries: Indonesia, Vietnam, and Thailand. Four randomly selected measurement locations were chosen in each country, with two locations in densely populated areas and two others in low-density areas. The sample data of PM2.5 concentrations were analyzed using nested factor analysis of variance, which allowed the relationship between the taken parameters, namely country, location, and population density classification, to be determined. The results revealed that all parameters had a significant influence on PM2.5 concentrations.

Abstract

This article discusses the modeling and analysis of Photovoltaic (PV) modules with irradiation and temperature variations using simulation technology. Modeling is carried out on solar modules through the p-n junction principle, a PV module model with temperature independence of photocurrent sources, diode saturation currents, and series resistances based on the Shockley diode equation. The photovoltaic process of solar radiation, PV cells convert a portion of the photovoltaic potential directly into electricity with I-V and P-V output characteristics. Electromagnetic radiation from the sun's energy is converted into electricity through the photovoltaic effect. The photovoltaic module simulation process with Matlab/Simulink, is carried out to observe the performance through the I-V and P-V characteristics of the solar module. The model, which is developed in a user-friendly manner using the Simulink block, shows the results of the PV characteristics when irradiation increases, the output current increases and the output voltage also increases. This results in a net increase in power output with increased irradiation at constant temperature.
